Online perforating device

The utility model discloses an online perforating device, the device are used for punching once more to the side wall to the in -process that cuts the process conveying after the calendering process, and the main part includes base and transparent box, and transparent box is installed on the base through its inside support column that is parallel to each other, support column one end and base threaded connection, and the other end passes transparent box upper surface and passes through nut locking, transparent box upper surface bilateral symmetry installs two cylinders, cylinder body downwardly extending is followed to the inside piston rod of cylinder, passes transparent box upper surface, and lower end of the piston rod passes through a nut fixed mounting needle plate base, surface parallel sets up on needle plate base and the transparent box, and surface mounting has the faller of perforating needle under the needle plate base. The utility model has the advantages of: this device punches to the side wall to the in -process that cuts the technology conveying after the process in the calendering once more, can avoid because high temperature makes hole shrink etc. And unable phenomenon of discharging gas to go, and the exhaust effect is better, reduces the production of steeping on the side wall.
